Application November '7, 1941, Serial No. 418,121

1 Claim. (Cl. 155-95) This invention relates to stools of the typehaving revoluble seats.

I-Ieretofore, the constructions employed to give the seat the desiredfree revolubility were complicated and expensive and invariably the seatwould tilt on its pedestal causing a generally insecure and oftenunsightly condition.

It is, therefore, an object of the present invention to provide a simpleand inexpensive manner of mounting the seat on the pedestal whereby theseat is at 'all times freely revoluble and the objectionable possibilityof tilting of the seat is entirely overcome.

With the above and other objects in view which will appear as thedescription proceeds, this invention resides in thenovel construction,combination and arrangement of parts substantially as hereinafterdescribed, and more particularly defined by the appended claim, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

The accompanying drawing illustrates one complete example of thephysical embodiment of the invention constructed in accordance with thebest modes so far devised for the practical application of theprinciples thereof, and in which:

Figure 1 is a side view of a stool embodying this invention Figure 2 isan enlarged view partly in side elevation and partly broken away and insection to show the construction of the seat mounting; and

Figure 3 is a perspective View of the seat and upper portion of thepedestal disassembled to better illustrate the details of construction.

Referring now particularly to the accompanying drawing, in which likenumerals indicate like parts, the numeral 5 designates a pedestal uponwhich a seat 6 is revolubly mounted. The ped-h estal consists of fourlegs l which may be made of any desirable material but are preferablyformed of Wood, and a spider-like casting or head member 8 to which theinwardly-curved upper ends of the legs are secured. This spiderlike headmember has four arms at right angles to each other with theirundersurfaces formed as channels to receive the upper ends of the legswhich as best shown in Figure 2 are bolted to the arms.

A foot rail 9 connects the lower portions of the legs to strengthen thepedestal and provide a footrest.

Formed integrally with the head member and connected to the extremitiesof the four arms is an annular track I0.

The seat 6 consists of a round baseboard Il upon which an upholsteredtop l2 is secured. The sides of the seat covering extend down around thebaseboard ll to be secured to the undersurface thereof and provide aneat, finished appearance.

A kingpin i3 fixed in the center of the baseboard extends down into ahole I4 in the head member to freely, rotatably connect the seat to thepedestal, disassembly of these parts being prevented by a cotter pin I5passed through the lower end ofthe kingpin. The kingpin, however, merelyserves to hold the head assembled with the pedestal.

The actual support for the seat is provided by four circumferentiallyspaced rollers i6 mounted on the lower surface of the baseboard ll inposition to run on the annular track IU.

The attachment of the rollers to the bottom of the seat may be effectedin any manner. In the present instance, the rollers are received inrecesses or openings Il in the baseboard and are freely journalled onaxles I8 secured to the underside of the baseboard.

From the foregoing description taken in connection with the accompanyingdrawing, it will be readily apparent to those skilled in the art thatthis invention provides an exceedingly simple manner of revolublymounting the seat of a stool on its pedestal, and that by Virtue of thisnovel construction, the seat will be at all times free to revolve andwill not tilt out of its proper horizontal position.

What I claim as my invention is:

A stool of the character described comprising:`

a head casting having an outer rim and radial spokes, the outer rimhaving a flat top surface providing a circular track; side angesprojecting down from the side edges of each of said spokes to formchannels; projections extending down from the spokes' at the hub portionof the head casting and between the side flanges, said projections beingequispaced from the center of the head casting; legs having their upperend portions curved inwardly and substantially horizontal, saidupper'end portions of the legs being received in the channels at theunder sides of the spokes and abutting said projections to be properlylocated thereby; means securing said upper end portions`of the legs tothe spokes; a pivot pin projecting up from the center of the headcasting; a seat connected to said pivot pin so as to be freely rotatablyconnected thereby to the head casting; and a plurality of rollerscarried by the seat at the under side thereof and arranged in a circleto run on the circular track, the axes of said rollers being radial tothe pivot pin and being spaced upwardly above the bottom of the outeredge of the seat a distance equal to at least one-.half the diameter ofthe rollers whereby said outer edge portion of the seat conceals therollers and the track.
